Abstract
1. Venous compliance and plasma volume were measured in thirty-one continuously normotensive women early (11-20 weeks) and late (31-40 weeks) in pregnancy and following delivery.
2. Mathematically fitted pressure/volume curves, obtained by venous occlusion plethysmography, were analysed according to two describing functions (i) the peak of the first derivative dv/dp max and (ii) a work index, ∫2510p dv.
3. The relationship between venous/volume factors seen after delivery, was disturbed during pregnancy, at which time the work index provided evidence for decreased venous compliance.
4. Pregnancy could be regarded as a potentially hypertensive state, brought about by a vascular/volume mismatch.
